i Letters Patent Na. 94,390, dated August 31, 1869.

IMPROVMNT IN mms.

'L'he Schedule refen'ed to in these Letters Patent and making part ofthe same Toiall whom it 'may concern:

Be it known that I, O'r'ro BRCK, of the city, county, and State of NewYork, have invented a new and useful Improvement in Fans; and I dohereby declare the following to be a full, clear, and exact descriptionthereof, which will enable those skilled in the art to make and use theSame, reference being had to the accompanying drawing, forming part ofthis specification, in which drawing- Figure 1 represents a front viewof this invention.

Fignre 2 is a longitudinal section of the Same.

Similar letters indicate corresponding parts.

This invcntion relates to an improvement on a telescopic fan, for whichLetters Patent have been granted to me, November 19, 1867.

In this patent, I have described a fan, which is. drawn out of itstubular case by means of a string.

My present improvement consists in combining with .the tubulartelescopic case of my fan, two Springs and a catch, in Such a mannerthat when the fan is drawn into its case, it can be locked and retainedby the catch, but as soon 'as' the cat-ch is released, the fan fiies outspontaneously.

A represents myfan, which is constructed of muslin, Silk, 4or othersuitable textile or flexible fabn'c or material, so that it will readilyfold up or expand, as may be desired.,

The inner, or but-end of the fan, is gathered up into a-head, a, whichiS placed into the inner tube b, being connected to the same by one ormore Springs c, of India rnbber, or any other suitable mateiial.

The tube b Slides in and out in the-outer tube or handle d, and it isconnected to the same by one or more Springs, e, of India rubber, or anyother suitable material.

The outer endS of the fan are connected to the tube d, as shown in fig.1.

To the head a' of the fan are Secured a button, f, and

a cord, g, or, instead of the button, a simple knot in the cord g may beuserhas will be presently explained.

The' bottoin end of the onter tube or handle-d is closed by a head, h,which is provided with a pearshaped slot, the large portion of which isof such a diameter that it allows the .button or knot to pass freely,while its small portion is too'narrow to allow said button or knot topass;

If the fan is free to follow the action of the Springs c e, it assumesthe position shown in the'drawing, the

head of the fan being carried up to the outer end of the tube b, as faras the connectlons between Said fan and the tube (Z will allow, and thetube b being drawn,

'out of the tube d until arrested by the connection of the fan with saidouter tube.

By pulling the cord g, the fan is drawn into the inner tube b, and theinner tube recedes into the outer tube, and in this position Vit can belocked by causing the button or knot f to catch in the narrow part ofthe slot i; but as soon as the button iS released from Said narrow part,the fan fiies out spontaneously and reaSsumeS the position shown in thedrawing.

It is obvious that the button and Slot may be replaced by any spitablecatch capable of retaining the fan when it iS drawn in.

I (lisclaim everything shown and described in my patent of November 19,1867; but having thus described my invention,

NVhat I claim as new, and deSire to secure by Letf ters Patent, is-- Thecombination of Springs c e with the tubes b d and fan A, and with acatch capable of retaining the fan when dra'wn in, substant-ially a-SSet forth.

OTTO BROK.
